In this cool bouquet for a gloomy spot, we combine lime-leaved coleus and silver-edged tulbaghia with euphorbia and golden bidens, both of which will keep on blooming whatever the weather. It’s ideal for a shady window-ledge, steps or a low wall, as it needs only a few hours of sun a day to maintain its lush and flowery look.
For added drama, try substituting the variegated tulbaghia with black lilyturf, Ophiopogon nigrescens.
Position the window box where you want it, place a layer of crocks at the bottom, then three-quarters fill with compost. Arrange the plants, firm well and top up with compost, then water well.
